Notes:
a
Assuming solution densities to be the same as those of pure water at the same temperature (ref 1).
Method/Apparatus/Procedure:
The apparatus is similar to an earlier design (ref 2) and is described in detail in the paper. 100-200 cm of (2) and 10-20 cm
3
of liquid (1) were placed in separate but connected thermostatted flasks. After thermal equilibrium was established a recirculating stream of air was used to vaporize liquid (1) and to transport the vapor to the flask containing (2). Five 10 cm
3
aliquots were withdrawn into separatory funnels. The concentration of (1) in (2) was then determined by extraction into chloroform followed by UV-spectrophotometry. Standards for the spectrophotometry were prepared by weight from pure liquid solutes.
Source and Purity of Materials:
(1) Analytical reagent grade (Wako Pure Chemical Ind. Ltd.), no stated purity, used without further purification.
(2) Redistilled; no further details given.
Estimated Errors:
Solubility: see table, type of error not specified.
Temperature: ± 0.01°C.
